Attitude Control for Reentry Reusable Launch Vehicle

This paper investigates the robust feedback control problem associated with finite time attitude stabilization of a reentry reusable launch vehicle subject to plant uncertainties and external disturbance. An integral terminal sliding mode is proposed firstly to achieve finite time stability in the sliding mode. Then, a robust attitude control for a reentry reusable launch vehicle is derived using the designed integral terminal sliding mode, and the attitude of the reentry reusable launch vehicle can converge to the equilibrium in a finite time with composite actuators. Numerical simulations illustrate the reentry reusable launch vehicle performance obtained under the proposed controller.
